Concept explainers
(a)
Interpretation : We need to comprehend the difference between an ionic bond (salt bridge) and a disulfide bond.
Concept Introduction : Proteins are
(b)
Interpretation : We need to comprehend the difference between alpha helix and ß-pleated.
Concept Introduction : Proteins are biomolecules which are composed of amino acid molecules. Here amino acids are bonded with each other through peptide linkage. Peptide linkage is formed between −NH2 and −COOH groups of amino acids with the elimination of water molecule. Hence each step of formation of peptide bond is a condensation reaction.
(c)
Interpretation : We need to comprehend the difference between tertiary and quaternary structures of proteins.
